Energy Conversion at Surface & Interface

In the world we live in, there are energies such as mechanics, motion, heat, light, and electromagnetism, and understanding these properties and controlling the conversion in the energies gives people life richness and depth, and a better society. 

The interface where the surface in different states touches is the place where the energy conversion occurs, and we will clarify the properties of the surface and interface and the mechanism of the chemical reaction that occurs there, and construct a method for further control.

For example, the interface between a solid and a liquid becomes a field for various chemical reactions. At the interface, atoms and ions in a solid and molecules in a liquid interact with each other, which may change the surface of the solid and the state of the liquid. New functions can be created by capturing and controlling the state of the interface.

Further, in rechargeable batteries which play an important role in the current energy conversion technology, it is known that the physical properties of the electrode surface and the chemical reaction occurring at the interface between the electrode and the electrolyte have a great influence on the battery performance. However, many points are unclear about the electrode surface of the rechargeable batteries having a complicated structure and the interface between the electrode and the electrolyte. These will be elucidated by methods using probes, light, electrons, etc., and based on the results, a method for enhancing reactivity will be constructed.
